MBA Purely for networking

Hi fellow apes,

I'm applying to grad school right now, and the sole reason I'm going is to network my a** off. I work for a family company (i'm in the family) and plan to stay with the company long-term. 

Is it reasonable to disclose the relationship in my interview and essays or should I keep it humble and pretend like there's no relationship? I definitely work hard and have earned my stripes but just wondering everyone's thoughts. 

Thanks
